SUB-GEOUP (E). 
This condition is brought about by a summer type depression, or a 
secondary to either a summer or a winter type one, passing L'Agulhas. 
Should the actual reading at L'Algulhas be the lowest, then there may be 
a prospect of rain. Should Clanwilliam actually be the lowest, then there 
is little prospect of rain, as it is a summer type depression, uninfluenced. 
The same applies if the Royal Observatory be the lowest. 
DIVISION (1). 
Section (a). — This happened upon 4 occasions, and rain followed 
2 of them ; wind was west for rain, but divided between west and east 
for dry weather. On one of the two dry days rain was expected and 
came at L'Agulhas. 
Prediction. — Wet weather. 
Section (b). — We have no cases of this condition. 
Section (c). — Here we get only 4 cases ; rain followed upon 2 
with west wind, and dry weather upon 2 with north winds. In neither 
of the 4 cases was rain expected. 
Prediction. — Dry weather. 
DIVISION (2).
